I chose to buy my custom PC from UK Gaming Computers for a few different reasons:
Firstly, their website and easy to use customisation compatibility checker were extremely useful, as was the advice that I was given over email. I had also heard that their customer service was fantastic - It was, I was kept updated at each stage of the build and their emails often explained small but appreciated details about the process.
Having received my computer I have to say that I am incredibly happy with the results. I am able to run the games that I have been wanting to play for quite some time - I'm currently playing through The Witcher 2 on high graphical settings - and the overclocking service has notably strengthened the capabilities of an already fairly robust machine.
I will be recommending UK Gaming Computers to anyone who asks me about getting a custom PC, and I would like to thank the team for their work.
